> 3 dayDer Geräuschpegel hängt zum einen von der Spannung ab mit der die Lüfter betrieben werden. 7,5 Volt find ich echt leise. 9 und 12 Volt sind schon merklich lauter. Allerdings darf man nicht vergessen Strömungsgeräusche nicht vom Läufter kommen sondern durch ungünstige Luftwege kommen, z. B. zu kleine Luftauslässe. Ich bin mit den Teilen zufrieden, habe auch noch andere Modelle vim selben Hersteller.

09-06-2025Avevo un minipc con J3455 in case LC-Power LC-1350MI a dissipazione passiva, sotto carichi leggeri arrivava a 65-70 gradi, niente di grave, ma non mi piaceva comunque.

> 3 dayParfait pour rendre la tête dextrusion de votre Creality CR-10 silencieuse , et remplace le ventilateur dorigine très facilement .

> 3 dayCant really say enough about this fan. Even if it does not pump as much air as others, its quality is unrivaled. 6 year warranty, in todays age its hard not to support one of the last companies that stand by there products. 6 years is as good as a new car warranty, and this is a $15 fan.

> 3 dayLe ventilateur ne fait aucun bruit, idéal pour une imprimante 3D, tourne vite et ne fait pas de vibrations. Et je compte men racheter un deuxième.

> 3 dayIf you require a fan which is 10mm thick, this one will NOT work.

> 3 dayMolto silenzioso. Adesso compro altre e cambio anche le ventole che fanno ancora tanto rumore

Greater than one weekAllinizio ero preoccupato perché non sentendo alcun rumore credevo di averla collegata male, invece era funzionante ma impercettibile come rumore! Noctua è una garanzia!

> 3 dayBearings began to grind less than 2 months after installing it. this is supposed to be a silent fan and makes more noise than my cheap 1 dollar 40mm fans.
Featuring advanced aerodynamic design measures such as Flow Acceleration Channels and Noctua’s AAO frame, the NF-A4x10 FLX is a highly optimised, premium quality quiet fan in 40x10mm size. Smooth Commutation Drivetechnology and Noctua’s reference class SSO2 bearings ensure superb running smoothness and excellent long-term stability. Topped off with modular cabling and a Low-Noise Adaptor and OmniJoin Adaptor Set, the NF-A4x10 is a premium choice for the highest demands.
AAO frame
Noctua"s AAO (Advanced Acoustic Optimisation) frames feature integrated anti-vibration pads as well as Noctua"s proprietary Stepped Inlet Design and Inner Surface Microstructures, both of which further refine the fan"s performance/noise efficiency.

|---|---|---|---|
Flow Acceleration ChannelsThe NF-A4x10 impeller features suction side Flow Acceleration Channels. By speeding up the airflow at the crucial outer blade regions, this measure reduces suction side flow separation and thus leads to better efficiency and lower vortex noise. |
SSO2 BearingThe NF-A4x10 features the further optimised second generation of Noctua"s renowned, time-tested SSO bearing. With SSO2, the rear magnet is placed closer to the axis to provide even better stabilisation, precision and durability. |
Integrated Anti-Vibration PadsIntegrated Anti-Vibration Pads made from extra-soft silicone minimise the transmission of minute vibrations while maintaining full compatibility with all standard mounting systems and fan clips used on heatsinks. |
Inner Surface MicrostructuresWith the tips of the fan blades ploughing through the boundary layer created by the Inner Surface Microstructures, flow separation from the suction side of the blades is significantly suppressed, which results in reduced blade passing noise and improved airflow and pressure efficiency. |
Reduced motor hub size
Thanks to its streamlined, compact motor design, the NF-A4x10"s motor hub is smaller than with conventional 4cm fans. This allows for more blade surface area and thus contributes to the NF-A4x10"s superior airflow and pressure performance.
